Hi Sheldon,

You keep saying that there is some problem using the ammonia
technique on aluminum.

The first time I read that, I was curious, and so checked it
out with some care.

In fact, aluminum is used in contact with ammonia in all
sorts of industrial applications (most relating to
refrigeration) precisely because it is not harmed as would
be certain other metals.

It is obvious (both from my reading, and from my own
reasonably extensive experience) that there is no problem
whatever using the ammonia technique on aluminum cookware.

All the best,
